Sunday 5th May 1985
Bill Elliott set a 500-mile race record, winning the Winston 500 held at Talladega Superspeedway, Alabama (US), at an average speed of 186.288 mph. Elliott won the race despite losing nearly two laps during a lengthy early pit stop to fix a broken oil line, and despite the race only having two caution flags. Elliott made up the entire distance he lost under one lengthy, green-flag period. The record stood as the fastest 500-mile race of any kind until 1990, when Al Unser, Jr. broke it by winning the CART Michigan 500 at Michigan International Speedway at an average speed of 189.727 mph. Mark Martin later broke the record for fastest 500-mile NASCAR race.
